Best germination condition is cool moist shade. Sow in pots or flats outdoors in fall, germinates in spring. Alternately, sow in pots or flats, place on heat mat at 75-80˚F for 2 months, cold stratify at 40˚F for 3-5 months in shady north facing location, return to greenhouse in warm sunny location back to heat mats, should germinate in 1-2 months. Elder seedlings will not germinate properly in sterile soil. Sow in rich compost. Fungi produce gibberellic acid, a growth hormone helpful for germination. Grow in shaded place in pots the first year before transplanting out, best location is as understory of larger tree. Grow three plus plants for pollination. Store seeds refrigerated at 41˚F if not planting. Soil pH 6.1-7.8. Hardiness zones 3-10. Perennial.
